I think we all know that weight needs to be done real soon.
The easiest way to do this should be everything has weight (obviously) and containers have a weight as well as the items in them.
Example:
A wicker basket weighs 1HG (Haven gram) and has a minimum 1 str requirement to lift.
Someone puts 40HG in it so it now weighs 41HG total, and would require say 18 str to lift.
This could fix the complaints about cupboards not being liftable, even with 1 seed in them.
It also shouldn't be too hard to implement, it's just 1 variable added to each item and container, and a global equation that everything refers to when lift is used.
